The CSC says the development of the R-Module Version 2.1 follows the numerous feedback that was provided to the council by stakeholders wishing to create transparency and credibility and to lead the recycled concrete dialogue.

As with the previous R-Module version, using at least 10% of R-Material is required for a concrete product to be eligible to carry the R-Module. Dependent on the R-material content, up to four Stars can be obtained:

Concrete producers holding a CSC certificate at the level Silver or higher can get certified according to the new R-module. All details regarding plant and product requirements, which a R-module certificate holder needs to comply with are described in the updated R-Module Technical Manual. The Manual can be downloaded here

The CSC R-module is expressed in the certificate by a supplementary “R” label and the number of Stars awarded.
